GZIP validation inside WHM

[toplisek]

I have set GZIP validation and need to know if this can be executed inside terminal as Linux command:

curl -X HEAD -I -sH 'Accept-encoding: gzip' Example Domain | grep content-encoding curl -X HEAD -I -sH 'Accept-encoding: br' Example Domain | grep content-encoding

Hi toplisek,
Yes, those curl commands can be executed in the terminal to see the site is enabled with GZIP and brotli compression.
Also you could find of online checkers to find the compressions enabled in the site/server.

Thanks.

I have tested and it is without any result for the above query inside account.

curl -X HEAD -I -sH 'Accept-encoding: gzip' Example Domain | grep -i content-encoding curl -X HEAD -I -sH 'Accept-encoding: br' Example Domain | grep -i content-encoding

The header is Content-Encoding, so you need to use grep -i to get a match with content-encoding.

The easy way to diagnose something like this is to simply remove the pipe to grep part. Then you get feedback like

HTTP/1.1 200 OK
Content-Encoding: gzip
Accept-Ranges: bytes
Age: 333888
Cache-Control: max-age=604800
Content-Type: text/html; charset=UTF-8

Server: ECS (chb/0286)
X-Cache: HIT
Content-Length: 648

and it is obvious that content-encoding is not matching Content-Encoding.

@toplisek, as ecartz
said yes it
seems you haven't added '-i' option in grep that will ignore cases , else you have simply add it as grep Content-Encoding or grep -i content-encoding.

It works but I guess Pingdom Tools reports FALSE signal as GZIP shows 45/100 and after all tests cPanel works fine without any issue.
